How does the Surface weigh more than an iPad 3 when the iPad 3 had a high-res display and was already considered to heavy? Why does the Surface have a kickstand that is useless on your lap when typing? This is what hardware design is about. The delta in weight between the iPad3 and Surface is pretty close to zero (15 grams). Furthermore, while the iPad3 has the HiRes display the Surface does have a USB and MicroSD slot and a better feeling body material. And the kickstand is usable on my lap. Not as nice as a laptop, but I use it on my lap nearly everyday. I'm sure MS will get better at hardware and software but they should learn patience first instead of being so quick in attempting to jump both Apple and Google in product development. Actually they did the exact right thing, IMO. You don't get great at HW design by not shipping. The Surface is a very good product. Not great, but it will get better I'm sure. Much like the iPod and iPad.
